NAS Improves Research Code by Factor of Seven, Attaining Sustained Performance of 8.53 Teraflops

In collaboration with physicist James Freericks of Georgetown University, Sherry Chang and Johnny Chang of the NASA Ames Supercomputing (NAS) Division recently co-authored a paper on some impressive optimization and scaling work done on Freericks’ research code, NDMFTS. The paper describes NAS’ efforts to optimize and scale NDMFTS, ultimately achieving a 7.3-fold speedup and 8.53 teraflops (66% of peak) sustained performance on 2,032 processors–the highest sustained teraflop performance of any application run on Columbia.
